I have 2 DSP 6678 connected via Ethernet.
On both of them launched net stack with TCP/IP protocol.
Code for DSP0 Core0:
for (i = 0; i < 65536; i++)
{
receiv(buf, 2048);
send(buf, 2048);
}
Code for DSP1 Core0:
for (i = 0; i < 65536; i++)
{
send(buf, 2048);
receiv(buf, 2048);
}
Transmitting 65536*2048 bytes end other ~ 145 seconds.
Speed transmitting ~ 7,06Mbit/sec.
If I'm transmitting 65536*8192 bytes, when transmitting ends other ~ 334 seconds.
Speed Transmitting ~ 12,26 MBit/sec.
Ethernet speed = 1 Gbit.
Before load program I'm do System Reset => Scripts => C6678 Init Functions => Global Default Setup.
Why speed transmitting so low?
What i'm doing wrong?
P.S. Sorry for my bad English.
